Construction manual GNUBLIN Module-Rail-Relay

From GNUBLIN

Introduction

Before you commissioning the GNUBLIN Module-Rail-Relay you have to do some small soldering. First check, if all parts are correctly delivered.

Assembled and soldered PCB (SMD)

6 x 2 pin terminals (green)

2 x 14-pin sockets

5 x Jumper

4 x Relay G6D

3 x 3 pin connector

2 x 2 pin connector

Assembly

Now solder the parts in the following order:
Frist the pin connectors followed by the 14-pin sockets.
Then the relays.
Last solder the pin terminals. you can connect two of them before you solder them. See the following picture:

The figure below describes the module and its components to help you
with the placement of the components.

Now the module is ready to use.

Inbetriebnahme

When starting up it is important that the I2C address and the pull-up resistors are set. However, the pull-up resistors must only be set if only one module is connected to the Gnublin. Or otherwise, at least to a module the I2C pull-up resistors must be set. The following figure shows the configuration for a module on the I2C connector.

Then the module can be driven by means of Gnublin-PCA9555 software. The exact description can be found in the article below.
